Calibration gas in disposable cylinders are available at Industrial Safety Equipment. With the large number of toxic substances found in many workplaces, it's critical that calibrated gas detectors be present in certain locations to guard against potential accidents. In addition to toxic exposures, a real danger also exists for individuals working in confined spaces and areas where explosions are a possibility. Not only do these various detecting devices have to be in place and operate properly, but they also need to be calibrated regularly to ensure precise monitoring. With our wide selection of disposable gas cylinders, we're the preferred calibration gas supplier. This includes H2S calibration gas, CO2 calibration gas and dozens of others. In many workplaces, gas detection systems are so critical that testing with them against precision calibration gas could be a daily requirement.
